MapleSim Driveline Component Library Now Available

Maplesoft is pleased to announce the launch of the MapleSim Driveline Component Library, a collection of components for driveline modeling applications. Built with the involvement of several transmission manufacturers, this MapleSim add-on covers all stages in the powertrain, from the engine to the differential, wheels, and road loads, as well as vehicle dynamics.

With MapleSim, engineers develop high-fidelity, high performance models in a fraction of the time it would take with other tools.  By using MapleSim together with the MapleSim Driveline Component Library, engineers can mix the best of physical models and empirical data to maximize model fidelity, optimize designs, and improve overall vehicle fuel efficiency.

One major advantage of this library is that the components use an acausal approach to model development, where the user can simply connect the components together in the required configuration without worrying about issues like torque direction and load flow. These issues are resolved automatically by the underlying solver. This makes it much easier, and significantly faster, to produce models of any complex transmission configuration from prebuilt components, compared to using traditional signal-flow simulation tools.

The library also provides an option that allows power losses to be readily incorporated into the model, either through external calculations or through the use of empirical look-up tables. For example, energy loss in the powertrain can occur due to tooth meshing, bearing friction, slip, and other factors.  This approach allows the user to maximize the fidelity of the model while introducing losses in a manner that best reflects how the loss data was acquired during testing.

Webinar: Modeling and Simulation of HEV and EV Power Electronics

This webinar covers new approaches to modeling and simulation for hybrid electric vehicle (HEV) and fully electric vehicle (EV) applications with a particular emphasis on power electronics design. HEVs and EVs present many new design challenges to engineers: They are complex multidomain, multi-body systems. In this webinar, multidomain and multi-body simulation techniques are used to place the power electronics components and systems into the context of the entire vehicle as it operates dynamically. That is, the power electronics are simulated in the same environment as the IC engine (if present), batteries, electric motors, driveline, tires, and chassis operating in three dimensions. FTP and EPA drive-cycles are applied to the vehicle model to determine the loading of the power electronics and the effect of various control strategies on overall metrics, like fuel efficiency. Symbolic computation techniques are used to automatically produce very fast model code for real-time simulation. This unified approach to full-system modeling and simulation results in more accurate vehicle models that are produced faster and yield better system-level insight.

Not only could he enter the equations as if writing by hand, ‘the fact that I can do symbolic calculations allows me to do optimizations that are virtually impossible with other software.’
Efficient development through physical modeling
Control Engineering, August 29, 2011
“Being able to design an adequate machine or system model plays an important role in simulation-based development. At the same time, mapping out all the dynamic characteristics of a machine can take a lot of time. "Tools for physical modeling such as MapleSim from Maplesoft provide optimal support and reduce the amount of time and work considerably," said Philipp Wallner, global technology manager at B+R.”
